Abstract
Described is a system for targeted waterflooding in an oil field. The system includes a mobile reverse osmosis unit connected with source water. The mobile reverse osmosis unit generates low salinity fresh water from the source water. An injection manifold is connected with the mobile reverse osmosis unit. The injection manifold distributes the low salinity fresh water into injection wells within the oil field. The low salinity fresh water is stored underground prior to its use in production wells.
Claims20
A system for targeted waterflooding in an oil field, comprising:
- one or more mobile reverse osmosis units connected with source water,
- wherein the one or more mobile reverse osmosis units generate fresh water from the source water, the fresh water having a salinity lower than the source water;
- an injection manifold connected with the one or more mobile reverse osmosis units;
- and
- a plurality of injection wells located within the oil field,
- wherein the injection manifold distributes the fresh water into one or more of the plurality of injection wells, and
- wherein the fresh water is stored underground prior to use in one or more production wells.
A method for targeted waterflooding in an oil field, comprising:
- identifying a target area in the oil field;
- positioning one or more mobile reverse osmosis units proximate to the target area;
- connecting source water to the one or more mobile reverse osmosis units;
- generating fresh water from the source water with the one or more mobile reverse osmosis units, the fresh water having a salinity lower than the source water;
- injecting the fresh water into one or more of a plurality of injection wells;
- and
- storing the fresh water underground prior to use in one or more production wells.
